Abstract

DISTILLATION PROCESS A MIXTURE CONTAINING HYDROGEN IODIDE AND WATER AND HAVING A WATER CONTENT OF NOT MORE THAN 5BY WEIGHT 5 (PARTICULARLY NOT MORE THAN 3BY WEIGHT) IN A DISTILLATION SYSTEM IS DISTILLED TO PREVENT CONDENSATION OF HYDROGEN IODIDEINTHEDISTILLATIONSYSTEM. THEMIXTUREMAYCOMPRISE HYDROGEN IODIDE, WATER, METHANOL, METHYL IODIDE, ACETIC ACID, AND METHYL ACETATE. EVEN WHEN THE MIXTURE CONTAINS 10 HYDROGEN IODIDE AT A CONCENTRATION OF 1 TO 3000 PPM ON THE BASIS OF WEIGHT, AN ACETIC ACID PRODUCT HAVING A CONCENTRATION OF HYDROGEN IODIDE OF NOT MORE THAN 50 PPM CAN BE OBTAINED BY WITHDRAWING A FRACTION CONTAINING HYDROGEN IODIDE F ROM THE TOP OF THE COLUMN, AND WITHDRAWING 15 ACETIC ACID AS A SIDE-CUT STREAM OR A STREAM FROM THE BOTTOM OF THE COLUMN. SUCH A PROCESS (DISTILLATION PROCESS) EFFECTIVELY INHIBITS CONDENSATION OF HYDROGEN IODIDE IN THE DISTILLATION SYSTEM AND CORROSION IN THE DISTILLATION SYSTEM. 3
